One note...the Zone kit does not come with any new frame to shackle bushings (I don't think any of the kits include these bushings). I had to order those separately. You'll probably want to replace them on an 18 year old Jeep. The fronts come off easily. The rears are a pain because of the gas tank. Either drop the gas tank or cut the bolt off. Others have weaseled them out, but I wasn't that lucky.

Also, I was able to sell my old springs to a guy doing an SOA conversion, so don't throw them away.
